Abstract

The invention provides a nanometer emulsion which is prepared by, mixing medicament, solvent oil and emulsifying agent, heating up to 60 deg. C, agitating, dispersing homogeneously, heating booster solvent with right amount of water to 80 deg. C for dissolution, keeping the temperature at 60 deg. C, charging aqueous phase into oil phase, high pressure dispersing, filtering, split charging, and sterilizing.

Description

A kind of novel pharmaceutical formulation---nano-emulsion and preparation method thereof
Technical field
The present invention relates to a kind of novel form of medicine, relate in particular to nano-emulsion and preparation method thereof.
Background technology
Some insoluble drugs, fat-soluble medicine and some Chinese medicine extract, relatively poor in the intravital absorption of people, bioavailability is low.Generally traditionally they are made emulsion, with emulsion as pharmaceutical carrier, but the particle diameter of this traditional emulsion oil phase is bigger, generally greater than 100nm, common emulsion is thermodynamic unstable system, needs energy during preparation, centrifugal back layering, and this emulsion easily produces precipitation in storage process, influences the curative effect of medicine.Nano-emulsion is the oil-in-water type emulsion body, oil phase is prepared emulsion through a sub-high pressure dispersing emulsification machine mechanical activation comminution in aqueous phase at least, the granularity of oil droplet is minimum, nano-emulsion and traditional emulsion have many similarities, as including water in the component, oil phase and surfactant also can be divided into O/W type and w/o type etc. on the structure.But they are diverse two states, exist difference in essence.At first in appearance, nano-emulsion is different from general emulsion, is transparent or slightly opalescent translucent, and viscosity generally approaches water and is far smaller than the emulsion of corresponding water-oil factor example; Secondly on structure is formed, the required surface-active contents of nano-emulsion is apparently higher than common emulsion. and about about 5%-30%, the existence that more needs cosurfactant sometimes could form nano-emulsion; The 3rd, nano-emulsion not as emulsion like that with the difference of type can only with oil phase or water mixing, nano-emulsion within the specific limits can with the oil phase mixing again can with the water mixing, nano-emulsion can be co-continuous phase form and exists in the definite composition scope; The 4th, the of paramount importance structural difference of nano-emulsion and emulsion is the size of particle diameter, and the particle diameter of nano-emulsion is even, and generally between 10-100nm, and particle diameter one Yin Dynasty of common emulsion is greater than 100nm, and skewness; The 5th, common emulsion is thermodynamic unstable system, needs energy during preparation, and centrifugal back layering, and nano-emulsion is a thermodynamic stable system can be placed and centrifugal not stratified for a long time.
Summary of the invention
The object of the present invention is to provide a kind of novel form of medicine---nano-emulsion and preparation method thereof.
Nano-emulsion of the present invention is a kind of oil-in-water structure, and the mean diameter of oil phase is less than 100 nanometers, have in the oil phase medicine with as in the solvent naphtha of adjuvant, emulsifying agent, cosolvent, antioxidant, the antiseptic one or more; Solvent naphtha is one or more in vegetable oil, animal fat, mineral oil, artificial oil, the silicone oil etc.; Emulsifying agent is one or more in polyglyceryl fatty acid ester, sucrose, fat, lecithin, tween, span, pluronic, silicone oil, carbomer, glycerol, the sodium lauryl sulphate; Cosolvent is one or more in polyglyceryl fatty acid ester, sucrose, fat, lecithin, tween, span, pluronic, silicone oil, carbomer, glycerol, the sodium lauryl sulphate; Antioxidant is one or more in ethylenediaminetetraacetic acid, disodium EDTA, dibenzylatiooluene, D-xylose, xylitol, glycine, alpha-tocopherol, α-tocopheryl acetate, inositol, ascorbic acid, sodium ascorbate, malic acid, hydroquinone, citric acid, succinic acid, phytic acid, sodium pyrosulfite, the potassium metabisulfite etc.; Antiseptic is one or more in Oleum Caryophylli, propylene glycol, sorbic acid, sorbic acid methyl ester, parabens, butyl p-hydroxybenzoate calcium, Sodium Methyl Hydroxybenzoate, Sodium Propyl Hydroxybenzoate, benzyl alcohol, the benzoic acid etc.
The present invention also provides a kind of preparation method of nano-emulsion dosage form, oil phase is come the very little emulsion of prepared sizes through a sub-high pressure dispersing emulsification machine mechanical activation comminution in aqueous phase at least, be filled in certain container by filling machine, make through sealing, sterilizing then, concrete steps are as follows:
(1), it is even medicine, solvent naphtha, emulsifying agent to be heated to 60 ℃ of abundant dispersed with stirring;
(2), cosolvent and suitable quantity of water are heated to 80 ℃ of dissolvings;
(3), under the condition that keeps 60 ℃ of temperature, while stirring water is dripped to oil phase;
(4), disperse, filtration, packing, sterilization are promptly through the high pressure dispersing emulsification machine.
Nano-emulsion preparation of the present invention can improve the dissolubility of insoluble drug, promotes the macromole water soluble drug in the intravital absorption of people, improves these medicines bioavailability in vivo.Nano-emulsion can contain different fat-soluble medicines simultaneously, improves the stability of some labile drugs; Because the particle diameter of nano-emulsion is little and even, can improve the dispersion that is encapsulated in medicine wherein, also can promote the Transdermal absorption of medicine.Nano-emulsion has great application potential as pharmaceutical carrier.Mainly have following advantage: (1) is the isotropic transparent or semitransparent liquid of tool, Thermodynamically stable, and can filter.Be easy to preparation and preservation; (2) different fat-soluble medicines of solubilising simultaneously; (3) viscosity is low, reduces the phlebitis in the clinical practice, can not cause pain during injection; (4) medicine good dispersion is beneficial to absorption, can improves bioavailability of medicament; (5) medicine that is easy to hydrolysis being made water-in-oil type nanoemulsion can play a protective role; (6) can prolong the drug release time of water soluble drug; (7) can increase transdermal absorption factor.
